Abstract: We derive the nonlinear gyrokinetic equation for axisymmetric Plasmas in its most general form, i. e. including finite ;3, collisions, drivingtoroidal electric Field, and, accordingly, non-Maxwellian, poloidally dependent unperturbed distribution functions. We rote the relation between the assumption of radial periodicity of the linear eigenfunction - the period being a multiple of the distance between rational surfaces - and the ballooning representation. We remark that this assumption is not justified in the presence of nonlinear interactions, and, fror there, suggest a possible saturation mechanism of the potentially dangerous toroidicity induced modes.
